Fig. 2. Distribution of mean brown stem rot (BSR) disease reactions (A) across two field locations and (B) in the greenhouse for a population of F4–derived soybean lines developed by crossing the cultivars Bell and Colfax. Genotypes of lines for Satt547 are designated by the shading of bars. BSR symptoms were a visual estimation of the proportion of stem pith tissue that was browned. The BSR disease scores for the parents are designated by the placement of their names on the figure.
